The expansion index laser sensor connection signal processing module, the signal processing module is configured with expansion index
Data Integration unit；
The signal processing module connects the DCS master control device.
Preferably, the expansion index laser sensor is configured that first sensor, the second sensing on each boiler to be measured
Device and 3rd sensor measure the top, side and bottom of boiler to be measured respectively.
Preferably, system further include: the alarm module of DCS master control device connection.
Preferably, the signal processing module is configured to laser signal and reference signal compares, and calculates phase-shift signal
Signal processing module.
It can be seen from the above technical scheme that the intelligence for being used to monitor boiler expansion index of the utility model embodiment
Real-time system, by by expand index laser sensor signal integrated and from signal processing module calculate and to DCS it is total
It controls device to upload, multiple boilers of power plant is monitored in real time, expansion index is obtained, with overall monitor boiler operation situation.
To reach the technical effect that measurement is accurate, monitoring is comprehensive, reliable for operation.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described.It should be evident that the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of for monitoring the intelligent real-time system structure of boiler expansion index disclosed in the utility model embodiment
Schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Current three-dimensional expansion indicator is usually very simple mechanical displacement structure, be by reading to obtain three on the spot
Dimension expansion numerical quantity, acquisition and storage function when not having more boiler acquisitions, teletransmission sum numbers factually, to the operating status of boiler
Real-time monitoring cannot be reached, operations staff cannot grasp operation state in time, and there are security risks.
The utility model provide it is a kind of for monitoring the intelligent real-time system of boiler expansion index, with realize to power plant whole
The technical purpose that boiler is monitored in real time comprehensively.
Fig. 1 show it is a kind of for monitoring the intelligent real-time system of boiler expansion index, including, it is multiple boilers 1 to be measured, swollen
Swollen index laser sensor 2, signal processing module 3 and dcs DCS master control device 4, in which:
Each boiler to be measured configures expansion index laser sensor 2；
The 2 connection signal processing module 3 of expansion index laser sensor, the signal processing module 3 is configured with expansion
Achievement data integral unit 31；
The expansion achievement data integral unit 31 will expand what index laser sensor 2 was exported on multiple boilers to be measured
Data are summarized, and complete to calculate by the signal processing module.
As shown in Figure 1, the expansion index laser sensor 2 is configured that first sensor 21, on each boiler to be measured
Two sensors 22 and 3rd sensor 23 measure the top, side and bottom of boiler to be measured, the expansion index laser respectively
Number, model and the allocation position of sensor, install according to actual requirement of engineering, do not do and limit to.
The signal processing module 3 connects the DCS master control device 4.
The DCS system is as the continuous of modern large scale industry production automation is risen with process control requirements increasingly
The complex control system that complexity is come into being, it is computer technology, system control technique, network communications technology and multimedia skill
The product that art combines.
It should be noted that the signal processing module 3 and the preferable DCS of connection type of the DCS master control device 4 are passed
Defeated route.
